IMPROVEMENT IN MACHINES FOR WIRING BLIND SLATS.

Specification forming part o f Letters Patent No. 132,141, dated October15, 1872.

To all whom it may concern:

Be it known that I, BIRAM C. DAVIS, of

i Binghamton, in the county 'of Broome and State of New York, haveinvented a certain Improvement in Machines for Wiring Blind- Slats, ofwhich the following is a specification:

My invention relates to single stationary blind-wiring machines, thatwire the slats on the rod, which is adjusted first to wire the slats,then again to connect the slats to the rod, making several handling ofthe slats. The object of my invention is to complete the wiring with onehandling` of the slats and rods. This I accomplish by giving a vibratingmotion to the main staple-driving part of the machine.

Figure 1 is a perspective view of the machine complete and ready foruse; Fig. 2 is a transverse section, showing the position when settingthe staple into the slats; and Fig. 3 is an end elevation ofthe saine,showing the position when connecting the slats to the rod.

This machine should be made of the usual material for blind-wiringmachines, and constructed so as to resist the strain of the operatingparts.

A is the bed-plate. B is the vertical standard in sections, which issecured to the bedplate A by means of the bolt G, as shown. D is themain staple-drivin g part of the machine, which I construct in the usualmanner, with lever E, driver F, staple-bar, staple-feeding device, andguides for conducting the staples to the slat and rod. This part D Ihinge to the upper section of the standard B, as shown at G. This uppersection is secured to the standard B by means ofthe bolt H. I is thespring attached to the upper section, which presses against the mainstaple-driving part D, throwing it out in line with the blind-slat J, asshown in Fig. 3. K is the screw that regulates the machine to set thestaple in the middle of the edge of the slats. L is the blind-rodattached to the notched gage M. N is the wire'rod that has at itsleft-hand end, as shown in Fig. l, a spring-pawl, O. P is the stop thatslides along on the rod N for the purpose 'of securing it at anyrequired distance from the staple guides for setting the stapleuniformly in the middle, lengthwise of the slats. Q is the coiled springon the wirerod N, which keeps it sprung to the left hand of the machine,and causing the spring-pawl O to catch in the notches on the gage M, fordrawing italong at the required place to attach the slat J to the rod L.R is the bedpiece, on which the slat rests while receiving the staple,which projects over the edge of the bench in an angle with the mainstapledriving part D, as shown in Fig. 2.

Operation.

The machine, Fig. 1, is secured firmly to a work-bench, and all partsbeing properly adjusted, and the blind-rod L attached to the notchedgage M, and then, by placing the slat J on the bed-piece R, and againstthe stop P, and, pressing it to the right hand, it operates the wire rodN and coiled spring Q, drawing the notched gage M and blind-rod L to theproper place for connecting the blind-slat J to the rod L, as shown inFig. 3; then the lever E is operated, forcing one staple in the edge ofthe slat J 5 this slat, on being released, the compressed coiled springQ throws the pawl O in the next notch, ready to draw the gage M alongagain. The spring S prevents the notched gage sliding back. On placingthe wired slat J across the rod L, as shown in Fig. 3, the staple in theedge strikes against a notch, as shown at T, and, by pressing with theslat, it carries the main stapledriving part D the distance of about ahalf inch to a perpendicular line to the middle of the blind-rod L, andalso compresses the spring I 5 then the lever E is again operated,forcing a staple, one prong through the eye of the staple in the slat J,into the rod L, connecting them together, as shown in Fig. 3, makingthat link complete, and in the operation of placing the next slatagainst the stop P, it releases the main staple-driving part D by thestaple passing out of the notch, shown at T; then the spring I throws itover to the edge of the slat again, as shown in Fig. 2, ready to receivethe staple, thus completing link by link throughout the whole length ofthe rod forming the panel of the blind.

I claim- 1. The combination of the staple-driving.
